IPC: G01K7/18
Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To simply and certainly exclude influence of thermoelectromotive force, when the resistance value of a resistor to be measured is measured by a four-terminal method. SOLUTION: As the first measurement, constant current I is caused to flow from a constant DC source 10 to the resistor X to be measured from its first lead L1 side toward the second lead L2 side, and voltage Va generated then in the resistor X is measured. Next, as the second measurement, the constant current I is caused to flow reversely to the resistor X this time, from the second lead L2 side toward the first lead L1 side. After voltage Vb generated then in the resistor X is measured, the average voltage Vc of the voltage Va and the voltage Vb is computed, and from this average voltage Vc and the constant current I the resistance value of the resistor X is found.

Title: Manufacture of semiconductor device
Inventor: FUKUSHIMA YASUSHI
IPC: H01L21/318
Filed: 1991-11-29
Abstract: PURPOSE:To eliminate a decrease in yield due to coating defect of photoresist and to shorten steps by reducing once the number of times of photomechanical processes by obviating double coating of the photoresist at the time of implanting impurities in the case of stopping a channel. CONSTITUTION:Photoresist 13 is selectively formed in an element forming region on a nitride film as an oxide film 8 and an insulating film 3 by photomechanical process. Then, boron (P-type impurity) is ion implanted as other conductivity type impurity for stopping a channel, and a boron-implanted layer is formed as other conductivity impurity implanted layer 14 on the surface of a P-well 12. In this case, the film 8 and the photoresist 13 become masks, and an impurity implanted layer 14 is not formed on an N-well 11 and the element forming region. Thus, since double coating of the photoresist is not executed at the time of implanting boron (P-type impurity) in the case of stopping a channel, a decrease in yield due to coating defect can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To produce a polymer dispersion type liquid crystal element having high reflectance. SOLUTION: A polymerizable compound containing a compound having a photodimerizable structure and plural polymerizable groups, a low molecular weight liquid crystal and a polymerization initiator for the polymerizable groups are mixed to prepare a polymerizable composition, and this composition is injected into a cell 30.

In regions in which the amplitude of the light 11 is small, polymerization and phase separation are caused to form polymer dispersion type liquid crystal layers 10 having a high refractive index.  When the resultant cell 30 is irradiated with polarized light 12, the low molecular weight liquid crystal in the cell 30 is aligned in a specified direction. The periodic variation of the refractive index of the layers 10 increases and the objective polymer dispersion type liquid crystal element having high reflectance is obtained.
